Commentary - Psalm 138:7-8

Bird's-eye view

In these concluding verses of Psalm 138, David moves from a broad declaration of God's glory and character to a deeply personal confession of faith in God's preserving and perfecting power. This is not abstract theology; it is battlefield theology, forged in the midst of real distress and opposition. The core of the passage is a robust confidence in God's sovereign commitment to His people. David affirms that God's intervention is not a matter of "if," but "when" and "how." He will act to revive, to defend, and to save. The psalm culminates in one of the great statements of assurance in all of Scripture: "Yahweh will accomplish what concerns me." This confidence is not rooted in David's own strength or faithfulness, but in the unshakeable, eternal nature of God's lovingkindness (hesed). The final plea, "Do not fail the works of Your hands," is therefore not the cry of a desperate man unsure of God's love, but rather the prayer of a beloved son, reminding his Father of a promise He is absolutely certain to keep. It is a prayer that argues from God's character back to God, which is the very essence of biblical faith.

These verses serve as a powerful anchor for the believer in any generation. They teach us that our security rests not on our ability to navigate trouble, but on God's determination to see His purposes through to completion. We are His workmanship, His project, and God does not begin a work that He does not intend to finish. The same hand that stretched out to create the cosmos is the hand that stretches out against our enemies, and the same right hand that saves us is the hand that will perfect us until the day of Christ Jesus.

Outline

Context In Psalms

Psalm 138 is a psalm of David, a song of thanksgiving and confident trust. It begins with wholehearted praise, offered "before the gods," meaning in defiance of all false idols and spiritual powers (v. 1). David praises God for His lovingkindness and truth, and for the fact that God has magnified His word above His very name, showing that God's promises are the most reliable thing in the universe (v. 2). He recounts a specific instance of answered prayer that strengthened his soul (v. 3) and then prophesies a day when all the kings of the earth will praise Yahweh (vv. 4-5). The immediate context for our verses is the contrast David draws between the high and lofty God and His care for the lowly (v. 6). It is because God has respect for the humble that David, in his own low and troubled state, can be so confident of divine intervention. The psalm thus follows a classic pattern: from personal praise, to global prophecy, and back to personal trust, grounding universal truths in the particular experience of a believer in distress.

Key Issues

God Finishes What He Starts

There is a profound comfort in knowing that our salvation, from beginning to end, is God's project. We are, as Paul says in Ephesians, His poiema, His workmanship, His masterpiece (Eph 2:10). When a master craftsman begins a work, he does not abandon it halfway through because he got distracted or because the wood was more difficult to carve than he anticipated. He sees it through to completion. How much more so the God of heaven and earth? The confidence expressed in this psalm is not the flimsy optimism of a man hoping for the best. It is the rock-solid assurance of a man who knows the character of the artist. David's logic is this: God made me, God saved me, and God has a purpose for me. Therefore, God will not abandon me. His reputation is on the line. His lovingkindness, His covenant loyalty, endures forever. The final prayer, "Do not fail the works of Your hands," is therefore one of the most secure prayers a believer can pray. We are not asking God to do something contrary to His nature; we are appealing to the very core of His being. We are asking Him to be Himself. And because He cannot deny Himself, we can be confident that He who began a good work in us will bring it to completion at the day of Jesus Christ (Phil 1:6).

Verse by Verse Commentary

7 Though I walk in the midst of distress, You will revive me; You will stretch forth Your hand against the wrath of my enemies, And Your right hand will save me.

David begins with a realistic assessment of his situation. He is not pretending that his life is easy. He says, "Though I walk in the midst of distress." The Christian life is not a playground; it is often a battlefield. Distress, trouble, affliction, these things are not on the periphery; they are right in the middle of the path. But the presence of trouble does not mean the absence of God. The promise is not that we will be spared from the walk through the valley, but that God will be with us in it. "You will revive me." This means to preserve life, to make alive. When the pressures of the world and the attacks of the enemy threaten to squeeze the spiritual life out of us, God breathes new life in. He does not just help us limp along; He revives us.

How does He do this? He acts decisively on our behalf. "You will stretch forth Your hand against the wrath of my enemies." God is not a passive observer. He is a warrior who intervenes. Notice that He acts against the wrath of our enemies. He deals with the root of the hostility. This is a picture of God's sovereign power over all opposition. No enemy, whether human or demonic, can act outside the boundaries that God has set. And when the time is right, His hand will stretch forth not just to restrain, but to defeat. Finally, "Your right hand will save me." The right hand in Scripture is the symbol of power, authority, and effective action. This is the hand of ultimate deliverance. It is the hand that brought Israel out of Egypt, the hand that steadied Peter on the water, and the hand of Christ that now sits at the right hand of the Father. This is not a hope of possible rescue, but a declaration of certain salvation.

8 Yahweh will accomplish what concerns me; O Yahweh, Your lovingkindness endures forever; Do not fail the works of Your hands.

This verse contains one of the most potent statements of faith in the Bible. "Yahweh will accomplish what concerns me." The old King James says He will "perfect that which concerneth me." This is a comprehensive promise. It covers everything that pertains to David's life, calling, and salvation. God has a plan for each of His children, and He will see that plan through to its glorious conclusion. He does not have abandoned projects. He does not have half-finished saints. He will accomplish, complete, and perfect His purposes for us. Our lives are not a series of random events; they are a story being written by a sovereign author who has already determined the final chapter.

What is the basis for such an audacious confidence? It is not in David's own grit or determination. The foundation is this: "O Yahweh, Your lovingkindness endures forever." The word is hesed, that great covenant term that blends love, loyalty, mercy, and faithfulness all into one. God's commitment to His people is not based on their performance, which wavers, but on His character, which is immutable. His lovingkindness is not a fleeting emotion; it is an eternal attribute. Because His love is forever, His purpose for us is secure.

On the basis of this eternal lovingkindness, David makes his final plea: "Do not fail the works of Your hands." This is not the prayer of doubt, but the prayer of faith. He is not wringing his hands, wondering if God might get tired and give up. He is taking hold of God's own character and promises and presenting them back to Him. He is essentially saying, "Lord, I am Your creation. You made me. More than that, You have redeemed me and begun a new work in me. I am Your project. Therefore, see it through. Finish what You started." And because we are the work of His hands, both in creation and in new creation, we can have absolute confidence that He will never forsake us.

Application

The application of these verses is direct and intensely practical for every believer. First, we must learn to be honest about our troubles. Like David, we can acknowledge that we are walking "in the midst of distress" without concluding that God has abandoned us. Faith is not pretending that problems do not exist; it is trusting God in the middle of them. Our circumstances are never the final word on God's faithfulness.

Second, our confidence must be placed in the right location. It is not in our strength, our wisdom, or our piety. Our confidence is that "Yahweh will accomplish what concerns me." This is a profound relief. The ultimate success of your Christian life does not depend on you. It depends on God. He is the one who will perfect, complete, and finish the work. This frees us from the twin sins of pride when we think we are doing well, and despair when we know we are failing. The outcome is in His hands, not ours. Our job is to walk in faith and obedience today, trusting Him with all our tomorrows.

Finally, we should learn to pray like David. We should ground our prayers in the character of God. When you feel weak, when you are tempted to doubt, remind God (and yourself) of His eternal hesed. Plead with Him on the basis of His own reputation. Say with the psalmist, "Lord, I am the work of Your hands. You have invested the blood of Your own Son in me. Do not forsake Your investment. Do not abandon Your project." This is not a prayer He will ever ignore. It is a prayer that flows from a heart that understands the gospel, and it is a prayer that He delights to answer.
